ADS7826IDRBTG4

Analog To Digital Converters (ADC) Overview

The ADS7826IDRBTG4 is a single-channel, 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates within an analog and digital supply voltage range of 2.7 V to 5.25 V. The device supports a maximum sampling rate of 200 kSPS and utilizes a 3-wire synchronous serial interface compatible with standard SPI protocols. Housed in an 8-lead SON package measuring 3x3 mm, it features pseudo-differential inputs and requires an external reference. Key performance metrics include a differential nonlinearity and integral nonlinearity of +/- 1 LSB, a power consumption of 800 uW, and a signal-to-noise and distortion ratio of 62 dB. The component functions reliably across an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm lead-free compliance status and exact pinout compatibility. Ensure the ordering quantity matches the required reel specifications. Confirm that the external reference voltage requirements align with the system design before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 10-bit resolution is sufficient for the application. Consider the 200 kSPS sampling rate limit and the requirement for an external voltage reference. Evaluate the 800 uW power consumption against system energy budgets. Verify that the 3-wire serial interface timing meets the host controller's capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7826 series of micropower ADCs. It shares architectural similarities with other devices in the family but is distinguished by its 10-bit resolution and specific packaging. The 'G4' suffix typically indicates lead-free manufacturing processes compliant with RoHS standards, differentiating it from older non-compliant variants.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes may include the ADS7826IDRBT without the G4 suffix if lead-free compliance is not strictly required. Other Texas Instruments SAR ADCs with similar resolution and speed should be evaluated for pin-to-pin compatibility and electrical parameter alignment.
